The dances that black people and wannabe black people do at certain gatherings that involve dancing, such as school dances, clubs, and even on the street. These "dances" are random movements of the body that look completely retarded as if they are having a seizure with style, but unfortunately everyone thinks it's cool because they are black. Black girls tend to do this the most, while their friends watch and say the phrases "that's hot" and "OOOoooooOOOstraight goods". The word "tribal dances" originates from the greek/latin word "tribalous o dancenous" and "dumbassous o dancingmoronous"
